Application filed December 6, 1922. Serial No. 605,240.

T 0 all whom it may concern:

Be it known that I, WILLIAM T. GAMES, a citizen ofthe United States,residing at Kansas City, in the county of ackson and State of Missouri,have invented certain new and useful Improvements in Phonographs; and Ido hereby declare the following to be a full, clear, and exact'description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters .of referencemai'kedthereon, forming part of this specification. a

This invention relates to phonographs of the type in which a number ofrecord-discs can be placed in alsuitable rack or carrier and each recordin turn will be placed on the turn-table and revolved, the tone armswung to position and the needle lowered upon the record; and after therecord is played the needle will be raised and the tone-arm swung clearof the record. The record will then be removed from the turn-table andplaced in the rack, and another record lifted from the rack and placedon the turn-table; all of which operations will 'be automatic, andcontinuous until the machine is stopped by shutting off the power.

The features of this invention are hereinafter fully explained andpointed out, and

are illustrated in the accompanying drawings in which:

In these drawings A, see Figs. 1, 6 and 7, indicates the frame of themachine, which is enclosed within the case ofthe machine.

At one side of the machine the frame A is at a lower plane than the restof the frame, in which are shaft bear-ings A and,

A see Figs. 6 and 7, andmounted in the bearing A is a short shaft B seeFig. 2", which supports a pair of spaced sprocket wheels B. Mounted inthe other shaft bearings A is another shaft B upon which is' supportedand secured a pair of spaced sprocket wheels B which are opposite and inline with the sprocket wheels B at the other side of the machine. Uponthese sprocket wheels is a pair of sprocket chains B The links of thesechains are provided with laterall projecting arms I), and I) see Figs.15 an 16, to which are secured, by rivets or otherwise, segmentalcross-bars b see Figs. 1, 2, and 2, there being suflicient space betweenadjacent bars 6 to receive a record disc I7 and b as shown in Fig. 2.

The arms I) of the chain links are provided with a laterally extendingbracket 6 on each side of the carrier, which brackets receive the loweredge of the large sized record discs. The segmental cross-bars securedto the arms 6 on each alternate cham link, are provided with brackets 25which are secured to the inner surface of the segmental cross-bars seeFig. 14;, and project through openings in the side walls of said bars sothat they will engage the lower edge of small. sized records when placedin the carrler. I

The shaft B is also journalled in a downwardly extending art a, of theframe A, and is provided with a. frictionally driven ratchet wheel 0,see Fig. 13, which'is secured on said shaft between the discs C and Gwith intervening f discs of packing 0 0 between them. The discs C and Care provided with hubs 0' by means of which they are non-rotatablysecured to the shaft B by means of transverse pins c and 0 the pin apassing through a slot in the shaft B The end of the shaft B is hollowand is closed by means of a screw-plug C and a s ring 0 is placedbetween the screw-plug 8 and the pin a, so as to press against said pinand thereby press the disc 0* toward the disc C and thereby compress thelayers of packing 0 0 against the ratchet wheel 0 so that therewill besufiicient friction to cause the shaft B to rotate to cause the endlessrecord carrier to move as hereinafter described.

The disc 0, see Fig. 11, is provided, around its periphery, with twelveratchet notches, six of which, a are not out as deep as the: remainingsix notches 0 The purpose and operation of these notches a and 0 will befully explained hereafter.

At the intermediate part of the frame A, see Figs. 6 and '7, areprovided journal bearings A and A, in which are placed rockshafts D andD of swinging brackets D and D see Figs. 1, 4, 14, 19 and 30. Theserock-shafts D and D are secured against longitudinal movement by meansof rings d placed on their inner 'ends, and secured thereon by means ofset-screws d. The

rings d are provided with ar ms d and d? see Fig. 32.

Attached to the arms d and d are springs d and (Z which have theiropposite'ends secured in cars a on the frame A so that the action ofsaid springs tends to swing the brackets D and D upwardly.- At each sideof the axes of rock-shafts D and D on the opposite sides of the frame Aare stops, a against which the brackets D and D contact to limit thedownward and upward movement of said bracket.

and E the chuck E being adapted to lift I the records from the carrierbars b and the chuck E being adapted to replace the records back in thecarrier bars, working alternately.

Inrthe hinge part D is placed a spring D in the manner usual in suchhinges, which operates to maintain the hinge normally open as shown inFigs. 1 and 19, and when the hinge is operated as hereinafter described,assists in lifting the chuck bodies back to their normal position.

These lifting chucks E? and E are duplicates, with the exception thattheir construction is reversed, so that they face each other. Theirconstruction is as follows, reference being had to Figs. 19 and 20, viz:

They are preferably partly circular, and

bowl shaped, with a segmental indentation ribs a between which arepivoted record gripping hooks a and 6 which are 019- eratcd by means ofconnecting bars 6 Pivoted in the center of the chuck body is a shaft Ewhich is provided with three radial arms 6} from each of which link barsa extend to and are pivoted to the ends of the connecting bars 6 Aspring E" is provided to operate the gripping hooks e and 6 to engage arecord disc. The shaft E is provided with an arm e from which a link-bar6 extends to one arm of a bell-.

crank lever E pivoted at the periphery of the chuck body, the other 'armof which ex tends over the upper end of the hollow hinge pin (Z \Vhenthe bell-crank: lever E is operated, as hereafter described, to rock theshaft E against the action of the spring E the gripping hooks e and 6will swing outwardly from the 'centerof the chuck body, the hooks ecompletely receding back of the face of the chuck, and the hooks 6swinging out into gripping position. If a large record is presented tothe chuck, the hooks and the mechanism released to the action of thespring E the hooks 6 will grip the edges of the record. 1

If a small record is presented, the a will swing inward as shown in Fig.20, and the hooks 6 will grip the edge of the record.

The face of the chuck is covered by a plate which is secured in place bymeans of screws 6 see Fig. 20 and which plate is provided with slotsthrough which the record gripping hooks e and e operate.

Pivoted inlhe lower side of the swinging bracket D is a bell-crank leverF, one arm of which extends under the lower end of,

, the hollow hinge-pin (Z and in said hingepin' is a rod (Z whichextends from said bellcrauk lever upwardly to the end of the bellcranklever E so that when the bell-crank lever F is operated the movement iscomniunicated to the chuck mechanism hereinhefore described. I

Upon stud-shafts F and F secured in the machine frameA, are bell-cranklevers f, f, and from one arm of each bell-crank lever f a link fextends to the upwardly extending bell-crank lever F, and from one ofeach bell-crank levers f links f extend to ears 7" on the lowerhinge-lugs E of the lifting chucks E and E3. The ends of the arms of thebell-crank levers and f to which the links f and f are pivoted, are onthe line of the axis of the rock shafts D and D" so that when'the chucksE and E are swung upwardly as hereinafter de hooks scribed, the links fand f swing si1'nultaneously without interference to their operation.

Mounted in a vertical journal bearing G in the frame A, isa spindle Grfor a'turntable G This spindle G is provided with a hub G at its upperend, around which is formed-skew gear teeth. Above the hub G is afriction disc g, upon which the turn table G rests. The under side ofthe turn xtable is preferably provided; with a recess to receive thefriction disc, 7, and by which it is centered on the spindle. The lower'end of the spindle G stands upon a ball g, see Fig. 30, which rests upona screwplug 9 In Figs. and 36 I-show a shaft mechanism for operating theseveral mechanisms of this machine which consists of theshaft H which ismounted in a suitable bearing ment in the bearing. Upon the shaft H, I

place a sleeve H which is provided with, a thrust flange h which entersa recess on the inner end of the bearing a and is retained k therein bya ring, a which issecured on the inner end of the bearing a preferablyby boltswhich pass through the body of the bearing a and ring a and arethreaded into the ring a, so that the sleeve H is secured againstlongitudinal movement, but is free to revolve. I

Adjacent to the inner end of the sleeve H there is a worm thread If. andon the inner end of the sleeve H are radial ratchets, or clutch teeth kUpon the shaft H, I then place a slidable sleeve clutch H through-thewalls of which are'longitudinal slots it, through which a transverse key7L passes, said key also passing through the shaft H, in which it issecured by a setscrew H The slots h, in the sleeve H being long enoughto permit the clutch. sleeve H to slide as hereinafter described. Eachend of the sleeve H is provided with. radial ratchet clutch teeth 71.which are gilapted to engage the teeth h? and the sleeve Upon the-innerend of the shaft H, I place a sleeve-shaft H one end of which isprovided With radial ratchet teeth H adapted to be: engaged by the teethk on the end of the clutch sleeve H and adjacent to said teeth H is aworm thread H and at the opposite end I provide a worm thread H ionbearing G, the worm thread H engaging.

the skew gear teeth G on the hub of the lac spindle G as shown in Fig.31. The spindle ..broken lines in Fig. 1. Upon the outer end of theshaft H, I place a pulley H upon which a belt, J, shown in broken lines,is placed, which is operated by a pulley J on a motor J When theclutch-sleeve. H is in the position shown in Fig. 35, and the motor isstarted, the sleeve shaft will revolve and cause the turn-table torevolve.

Under the turn-table there is the usual horn or resonator, J and uponthe upper end of this .resonator is the swivel J for the tone arm J Thisswivel J is constructed as follows, reference being had to Fig. 33, viz:

Upon the upper end of the resonator J is placed a ring j which isprovided with spokes j at the intersection, or hub, of which is avertical tube 7' and upon this ring 7', is placed a ring of felt j Uponthe ring j is placed another ring 9' which has an. internal spider jwhich supports a vertical tube J 6 which receives the tube 7' and swingsthereon. The ring j* is provided with clamp-ears j through which a.

clamp-screw 7' passes to secure the tone-arm J 5 firmly therein.

The ring 1' is provided with an arm J" by which the ring 9" and tone-armJ are operated as hereafter described.

, The tone armJ is provided with a vertically hinged extension J 8 whichis adapted to swing upon the pivot screws j, and upon this extension thesound box is secured.

Within the tone arm is a needle lifting lever K which is pivoted to thehinged extension J back of the pivot screw j, and has a short end iswhich engages the upper wall of the hinged extension. The long end ofthis lever extends backward to a point directly above the upper ends ofthe tubes i and J and from this lever a cord extends downward'ly throughsaid tubes, and through the resonator J shown by broken lines in Fig. 5,the lower wall (not shown) bein provided withan opening for said cord orthe purpose-hereinafter described.

The mechanism I have designed for actuating the several mechanismshereinbefore described, consists of a cam-shaft L,

' which is provided with a worm gear wheel shaft L with relation to eachother that the mechanism actuated thereby, will move in timed sequencewith relation to each other as will be hereinafter described. Thecamshaft Lv is mounted inv suitable bearings L on the machine frame A,see Fig. 3. L see Figs. 1, 4, 5, 14 indicates a transverse shaft securedin the bearing blocks L parallel with the cam-shaft L, and does notrotate. Upon this non-rotatable shaft L are canilevers 1 to 11inclusive, see Figs. 21 and 22, which illustrate the association of saidcams and levers. i

M indicates a feed shaft .see Figs. 1, 3, and 8 which is mounted in thebearing blocks L in the frame A, and is provided with a worm gear Mwhich meshes with the worm H on the shaft H and said'worm gear wheelbeing on the side of the shaft H opposite to the worm gear wheel L, isrotated by said shaft in a direction opposite to the direction ofrotation of the worm gear L. The feed shaft M is provided with a sleeveM which is free to rotate on said shaft. This sleeve M has securedthereon a cam sleeve M which has cam edges m, 922., against which aspring pressed roller N operates for the purpose of insuring the comingto rest of the sleeve M with the short arm m in the position thereofshown in Fig. 8. The sleeve M is provided with annular clutch teeth, mUpon the feed shaft M are splines m see Figs. 8 and 10*, upon which asleeve M is slidably placed, so thatwhen the shaft M revolves, thesleeve M must revolve with it. The sleeve M is provided with annularclutch teeth, m which are adapted to engage the teeth M on the sleeve Mas hereafter described. Upon the shaft M between the adjacent ends ofthe sleeves M and M is a spring M The sleeve M is provided withscrew-threads for the purpose hereinafter set forth. livoted' 1n theframe A is a U-sha'ped bracket 0, by means of a pin 0, and between thearms of said bracket a sleeve O v see Figs. 9 and 10 is mounted on a pin0. Upon the sleeve 0 a gear segment 0 is secured which meshes with thescrew-threads m on the sleeve M The hub 0'. see Fig. 10, of the segment0 is provided with stud posts 0 and 0 Secured to the frame A is astationarybracket N see Fig. 8 which is adapted to engage the stud post0 on the hub 0 '0 by means of the clamp 11, is anarm N in the free endof which is pivoted a link N the adjustment of the angular relationshipof said arm N and link N being regulated by means of a thumb screw n,for the purpose hereafter described. The link N is provided with asegmental plate N having thereon a graduation to indicate the degree ofangularity between the arm and link. 1

In the end r the link N3 rod 1v is piv- I 01?, see Figs. and 9,'ispivoted, which eX- tends to and is pivoted to the swinging bracket 0, sothat when cam 1 operates the cam lever 1 the swinging bracket 0 iscaused to swing to the position thereof shown by broken lines in F 8.The swinging bracket is moved in the opposite direction by a spring 0see Figs. 3 and.5, which is attached to the frame A. Pivoted to the camlever 2 is a rod P, see Fig. 5, which is connected to a lever P by meansof an adjusting swivel p. The lever I is fulcrumed on bracket 79 whichis secured on the frame A, and extends under the resonator J where thecord 70 see Fig. 33 is secured thereto, so that when the cam lever 2 isoperated by the cam 2 the sound box K will be raised sufiiciently tolift the needle out of contact with the record disc on the turn table Gas shown by broken lines in Fig. 33.

the rock shaft D.

To the cam lever 3 is pivoted a rod P by means of an adjustment swivel,which rod extends and is pivoted to the bell-crank lever f see Figs. 19and 19, by means of which, when the cam lever 3 is operated by thecam 3,the record gripping mechanism in the lifting chuck IE will be'opcrated,as

hereinbefore described.

To the cam lever 4 a rod P extends and is pivoted to the bell-cranklever f see Figs. 19 and 19, so that when the cam lever 4 is operated bythe cam 4, the power is exerted through the link f, see Fig. 19, tocause the lifting chuck E to swing from avertical to a horizontalposition on the swinging bracket D see Fig. 1 so that said bracket.

will be stopped by the lug a? at the left of To the lower end of the camlever 5. a rod P is pivoted and extends to and ispivoted to an ear 19see Fig. 19. on the upper side of the swinging bracket D see Figs. 1,and 19? so that when the cam lever 5 is-operated by the cam 5, theswinging bracket D will raise the lifting chuck F to a verticalposition.

Cam lever 6* is secured upon a shaft Q, mounted in the two intermediatebearing blocks L on the frame A, and on the rod Q, is a yoke Q, seeFigs. 35, 36,'and 37, for shifting the slidable clutch H on thedriveshaft H, out-of engagement with the shaft H and into engagementwith the sleeve H, for the purpose hereinafter described, so that whenthe cam lever 6 is operated by the engagement therewith of the short armengagement with the shaft H m on the sleeve M the cam lever 6 will causethe chuck sleeve H 'to be disengaged engages said cam lever 6 andoperates the same to again shift the clutch sleeve H into.

()n the shaft Q is an arm Q see Fig. 27, which is provided with inclinedsurfaces on the upper end thereof which meet on the center line thereof,and above the upper end of said arm is a spring pressed lever Q providedwith a roller 9 in the end thereof which operates to cause the arm Q tothrow the clutch sleeve either way, longitudinally.

The construction of the cam 6,-is as follows, see Figs. 23, 24, 25, 26,28, and 29. There are two parts; and The part 9' is non-rotatablysecured upon the cam shaft L by means of a transverse pin through saidshaft. At each side of the part L which connects said discs g to the camlobe 9 which operates in a recess g, see Fig. 24, in which is placed aspring 9 to yieldingly maintain the lobe in the position shown in saidfigure. Now as the cam shaft L rotates the cam. 6 in the direction shownin Fig. 22 it engages the cam lever 6 and operates said lever until thelobe g passes the lever 6 when the spring throws the lobe clear of theend of the lever 6 so that it can be swung back to its normal positionby the armQF; thisis necessary because at the instant the arm 9 operatesto throw the clutch sleeve H the cam shaft L and cams cease to revolve.k

Pivoted on the lever 7 is a rod 79 which extends and is pivoted to theswinging arm 12 see Fig. 5 mounted on the shaft B upon whichis pivoted aspring pressed ratchet dog 72 which is adapted to engage the ratchetteeth on the Y friction disc C, see Fig. 3. i

The cam 7 first engages the roller in the short arm of cam lever 7, seeFig. 22 which causes the'swinging arm 29 to swing upwardly so that thedog 79* will engage the second tooth on the disc C, and continuing itsrevolution the cam. Tengages the roller 'in the long arm of said camlever and forces it downward, which through the rod 30 and dog 39 causesthe disc C to revolve which by means of the friction caused by the discsC and C see Fig. 13 causes the shaft B to move the record carrierforward until the travel thereof is stopped by a record disc 6
